you fucking idiots and your 172hp stock thunder cat(which is a counter balance motor by the way) , and 100hp ancient 440 bullshit are so far off from what they actually made its fucking retarded! And for the guy who popped off about the 1100T and its POTENTIAL........ITS A FUCKING FOUR STROKE TURBO!!!!!!!!!!!!!! I openly admit I dont know shit, but MAYBE, JUST MAYBE, I might have a clue about what sleds do/dont have or are capable off.. I dont need to use google, I dont need to hear about what your buddies uncle used to own or what a so called "know it all sled shop" did........... The Thundercat NEVER made 172 off the shelf, a factory race prepped mid 90s (new compared to what your rambling about) with a full blown mod motor was LUCKY to see 100hp... If you havent a clue, do not spew!!!
